Itm 308bh1804 Bell Hanger Drill Bit 1/2 X 18 Inch

Product Description

The ITM 308bh1804 is a bell hanger drill bit designed for boring through wood and metal in tight or hard-to-reach spaces. Constructed from high speed steel, this bit measures 1/2 inch in diameter and 18 inches in length, giving technicians the reach needed to run wire, cable, or tubing through wall cavities and structural members. It is a standard tool for electricians, low-voltage installers, HVAC technicians, and plumbers who need to pass lines through framing without disassembling finished surfaces.

Bell hanger bits are commonly used in residential and light commercial installations where routing wire or small-diameter tubing through wood studs, joists, or composite materials is required. The 18-inch length provides adequate reach for most wall and floor framing applications. The 1/2-inch diameter suits a wide range of pass-through tasks including electrical cable runs, thermostat wiring, speaker wire, and small plumbing or refrigerant line access holes.

Key Features

• High speed steel construction for durability in wood and metal drilling
• 1/2 inch diameter for versatile pass-through applications
• 18-inch length provides extended reach into wall and floor cavities
